Cloud Foundry Scaling

I have a few basic questions around CF autoscaling that I am hoping someone can help with.

It appears that non-commercial Cloud Foundry does not provide auto-scaling out of the box. I realise I can use 'cf scale', but can CF emit custom events so that I can trigger cf scale?

I have seen another post that talks about auto-scaling by setting up an instance of an auto-scaler and binding the auto-scaler with the LRP, but I have seen other articles saying that there is no auto-scale capability in non-commercial CF.

And if I am deploying microservices, and those services use downstream services that I have not written, I would be relying on those downstream services scaling appropriately too?

And I assume I would be prevented from scaling beyond the limit of the 'space' anyway?

I see that Kubernetes provides auto-scaling, so I am thinking that perhaps that is a more scalable solution.

Thank you for any guidance.

App autoscaling is under development at https://github.com/cloudfoundry-incubator/app-autoscaler. I believe it's usable already.
It only scales your app, not downstream services (unless they are deployed as CF apps as well in your account).
The app auto-scaler does what cf scale would do, but automatically, so is still bound to the quota you have configured for your space and org.

you can find more resources regarding autoscaling here:

https://docs.run.pivotal.io/appsman-services/autoscaler/using-autoscaler.html

to scale an app you may use the command:

cf scale appname -m 512M

where appname is name of your application. Above command will scale the app to 512 MBs..
